Fox News Lifestyle spoke to experts including Department of Kinesiology's Dr. Jane Clark about the importance of getting children moving, not when they start to walk but just weeks after they're born. “What we know about development is that every stage builds one thing upon another and the brain-behavior relationships are built easier when you’re younger,” Professor Clark says in the article. “You’re not going to be physically active if the only thing you can do is walk,” Clark said. “If you don’t have the competence, you won’t have the confidence.”
